The effects of running on the body include increasing cardiorespiratory function, lowering body fat percentage, and strengthening bones and muscles. 1. Increase cardiorespiratory function: Running can increase lung ventilation and blood supply to the heart through repeated exercise of the heart and lungs, thus improving cardiorespiratory function. 2. Reduce body fat rate: long-term running is conducive to calorie consumption, so that the body fat, especially abdominal fat, is reduced, which is conducive to lowering the risk of high blood pressure, high blood fat and diabetes in the long run. 3. Strengthen bones and muscles: running can increase bone density, and at the same time, muscles and ligaments are exercised, which is conducive to maintaining the stability of the joints, thus avoiding sports injuries or degenerative joint disease. Exercise has other benefits for the body, and it is recommended to exercise more than four times a week for 40 to 60 minutes each time, mainly jogging and brisk walking.
